What is the shape of this data analysis?
Please answer all parts. Will rate, Thank you. A meat processing plant has 240 workers. 40 of them work in administration, while the remaining works on the shop floor. 80% of the people working on the shop floor use knives to cut whole animals into smaller pieces and to debone, putting them especially at risk of carpal tunnel syndrome (CTS). 75% of the shop people using knives have CTS, while 85% of the shopworkers who don’t use knives have no problems. 45% of the people working in the administration do a lot of computer work, putting them at risk of CTS as well, and 3 of them have CTS, while none of the others working in administration has CTS. Create appropriate tables and use them to calculate the following: a. Calculate the odds ratio of CTS for shop workers only b. Calculate the relative risk of CTS for shop workers only c. Calculate the odds ratio of CTS for all workers d. Calculate the relative risk of CTS for all workers

Dear students, In this Math Project, you will apply what you studied in chapter 3 in one real life suitable situation. Chapter 3 was about representing and describing data. The student should select a set of data of 40 measures like heights of 40 students, weights of 40 students, pocket money of 40 students, the income of 40 families, etc. After collecting the data, you should answer the following questions neatly and properly. 1) What type is the data you collected? Is it qualitative or quantitative? (It should be quantitative in this ptoject). 2) What type is the data you collected. Is it a continuous or discrete data? Why? Rush more information. 3) Find the arithmetic mean for the data you collected. What is the difference between the arithmetic mean and the geometric mean? 4) Arrange the data you collected in an ascending order and find the median. Show your working. 5) Find the mode of the data you collected. 6) Find the first quartile Q1? 7) Find the second quartile Q2? 8) Find…

Scenario: If 20 participants completed an attention task twice — once after consuming a sugar pill and once after consuming a pill that contained 25 mg nicotine, which test would be most appropriate? Assume data meets all assumptions for a parametric test, and that participant exposure to the sugar pill vs. nicotine pill were counterbalanced. Question: What is the research / alternate hypothesis for this scenario? Nicotine does not affect attention. Nicotine affects attention. Anxiety does not affect attention. Anxiety affects attention.
“Especially when conducting quantitative studies, it is important that one can distinguish between ‘constructs’ and ‘attributes’”. In the context of this statement, describe the difference between a construct and an attribute, but be sure to emphasise how the two are linked.
